Facebook muted my video

I made a video and put the music landslide to it by Fleetwood Mac I downloaded it off of iTunes and paid for it I bought it and then Facebook muted it I even put on the video that I do not own the rights to the song. I thought you could do that and I have done that in the past if you bought it off of iTunes and you also posted you do not own the rights to this song so how can they mute the video?
